Below, the same photo taken with the same exposure so you can get a handle on the relative brightness and color aspects of most of the major modes. Of course, since the exposures are the same, the brightest modes are a bit overexposed, especially Dynamic.
And as long as I'm mentioning Dynamic mode, although Mike did his usual "quick-cal" to improve the brightest mode, I must admit to not using it but for a few minutes. In my room, I found Living Room to still look better, and to be more than bright enough for my purposes. Mike's settings though, should be very useful to folks working in media rooms, family rooms...
The HC2030 and HC2000 lack the Auto image mode of the more expensive HC3020, but hey, how hard is it to switch from Natural - for best color, and movie viewing, to an even brighter Living Room or Dynamic mode!
As mentioned elsewhere, in my theater environment with the lights out, filling a 124" diagonal screen, even in 3D, Cinema had respectable brightness.
And the HC2030 should measure almost 40% brighter in 3D Dynamic, (based on the 2D measurements - we do not attempt to measure 3D brightness.)
Which reminds me, the HC2000 (the online version) claims only 1800 lumens, not 2000, and only 13,000:1 contrast not 15,000:1. What does that mean to you? Well, first, it's interesting that the HC2000 has less lumens and less contrast. Strange. Normally given the same projector, upping the contrast results in less lumens, not more. I therefore would suggest, that short of having an HC2000 to measure, that the two projectors are probably closer in brightness than their specs suggest.
Enough - let's move on!
